subject of the German Emperor, and a resi?V dent of Hermsdorf-untermlKynast, Germany,

have invented certain new and useful I m` provements in Roofing, of which the followi 1 ered, cannot make a roof weatherproof. 4

infr is a s ecification.

All the known' methods of covering a roof which shall beweatherproof do not answer their purpose. The disadvantage is that the single tiles are not connected together tightly enough to form a single fast body. Gonsequently in bad weather rst single tiles oi(` but the imperfect connection together of the` single tiles and rows thereof,"which could not prevent an up-and-down movement, caused;` the lines of mortar to break.V 'To obtain really storm and weatherproof roof, ajre-.,

sistant connection must be made. This has been tried already with various kinds of diagonal tiles or slates, ,which cover the lines of mortarentirely and arealso better con` nected together bylintroducing connectingtongues into suitably-formed grooves. VAlso" the use of projections engaging with the layer,

of tiles lying thereunder has been tried. The

connection-tongues have also been formed', dovetailed in order to keep the roof compari` atively tight if the ytiles or slates shonldbe' displaced; but all these ,different arrangements have not had the desired eiect, as the dovetail as well as the straight tongues with their grooves are much too long, being comtheir effect is contrary to their purpose, be cause they act as a lever and force the tiles lying above from one another, because the mortar cannot resist the pressure of the wedge duringastorm. Besides, such a system, even when all the lines of mortar areentirely cov- The object of the present invention is to obf tain'a roof which answers all'requirements by the use of tiles with special arrangements, so that a really weatherproof roof is produced, which bya peculiarlyarranged locking of the tiles is so connected together that the solidity already obtained is still further increased by a good mortar connection.

In the annexed drawings, Figure 1 is a plan view of the roof. Fig. 2 is a section on line I I of Fig. 1-that is, a section through a mortar joint. Fig. 3 is a section online II II of Fig. l; Fig. et, a section Online III III of Fig. 1. Fig. 5 shows a single tile. Fig. 6 is a section on line IV IV of Fig. 5; Figs. 7 and 8, sections onlines VV and-VIVI of Fig. 5.

"Fig, 9 shows ametal filling forthe cross-lines i of mortar. i

The roof is composed of'p/'wfshaped tiles,

AFig. f1.5 .'Ihe hollow"left sidefof each tile.

catches over 'the raised right edge ofthe next, 4so that the joining-line of mortar hasfalways a solid support and is held in the groove ct, Figs. 3 and 4. On the upper leftedge of each tile is a cut-out part b, Figs. l' and 5, of the saine width as the cross-line ofgmortar is intended to be, while the length of said cut-out part is such-that the `latter is" even with the right edge of the tile lying thereunder, Figs. 1, 2, and 5. The cross-lines of mortar being placed upon the upper borders of the tiles, Fig. l, there is thus a direct connection effected between the longitudinal and cross lines of mortar, so that the latter have a solid support at all points, because at the cut-out part b the tile thereunder forms the support. In Fig. I the longitudinal lines of mortar c and the crossflines d are represented by dotted lines, while in Figs. 2 and 4L their connection is shown. Such a connection of both said lines of mortar is very important from a tech-v nical point of view, because by the connection of these the roof is directly joined, so that it forms one solid body. The arrangement of the cut-ont parts b has the advantage that into the cross-lines of mortar long metal strips i can be placed in forming the cross-lines ofthe roof, In order to render the roof still more solid, two

vribs ff are arranged close underneath the lines of mortar,two on each tile,so formed that the free space lying between them forms a dovetail-shaped hollow g,l`igs.l, 3, 5, 7, and 8. Into this hollow g catch thev dovetail-shaped projections h, arranged on the under side of the tile until they come close to the lower end, Figs. 3 and S, sothat the whole roof is again joined inlines. -This joint isnot. at. all like. the projections on diagonal tiles hitherto used, because theprojections do not catch un-L der the joint of the two adjacent tiles, butk catch the middle of each tile,so that a displacementsidewise is vnot possible. lift aftile,the Winder-weather must destroy In order to boththe side -mortar lines and the junctionof 4them withthe respective cross-lines of mortar; but that is practically impos'sible,be
